0807.12.6 illustrate how gravity contols the motion of objects in the solar system

VOCABULARY WORDS


Gravity- an attractive force that pulls all objects toward each other
Law Of Universal Gravitation- the principle force of gravity acts between all objects in the universe
Mass- the amount of matter in an object
Newton's First Law Of Motion- the principle that an object will stay at rest, and an object in motion will stay in motion, unless an unbalanced force acts on an object
Inertia- the tendency of an object to resist a change in motion
Weight- a measure of the pull of gravity on an object

REDNECK DEFINITIONS


Gravity- a force that pulls stuff together
Law Of Universal Gravitation- the reason gravity happens
Mass- how much matter in the object
Newton's First Law Of Motion- the reson an object sits still and why it moves unless it is moved by something powerful
Inertia- the reason it don't move
Weight- a measure in gravity
